pokerroom seat

[MrWizard]

this is probably a dumb question, but does anyone have any theory on which character is best to be at pokerroom? Like which face is least trusted? Do people tend not to believe a bet from the fat character? You know what I'm getting at... does it matter? I know that there are more important things, i just read bisons article on seat choice, but this just occured to me as maybe relevant.
